Geolocation is one of the hottest trends in social networking today. Users enjoy connecting with friends at nearby locations. Businesses are beginning to take note of the opportunity to tie their brick-and-mortar locations to their online marketing.

As users provide more information about their location, serious privacy implications are beginning to surface. For instance, a Webroot study released in July 2010 found that more than half of survey respondents who used geolocation services were worried their privacy was at risk.
